Indo-Canadian porn star Sunny Leone rang in her 31st birthday on the sets of her first Bollywood movie "Jism 2" in Sri Lanka.

"Happy Birthday Sunny! Sunny celebrates her birthday with the unit members in Sri Lanka," producer Mahesh Bhatt posted on Twitter. Her birthday was on Sunday.

She cut a chocolate cake, which read "Happy Birthday Sunny".

Sunny, whose real name is Karen Malhotra, came to India for "Bigg Boss 5" last year. While she was a participant on the reality show, Bhatt offered her "Jism 2", and she gave her nod to it.

"Jism 2" is the sequel to 2003 film "Jism", in which Bipasha Basu's steamy scenes became the talk of the town.

Sunny will be seen with Randeep Hooda and Arunoday Singh. It is being helmed by Pooja Bhatt.
